TIRE

Patented June 30, 1908.

Application filed May 23, 1907. Serial No. 876,295.

To all whom it may concern:

Be it known that I, ARTHUR OBRIEN,'a

citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Tires; and I do hereby declare that the following is a full, description of the same, reference being hadlto the accompanying drawin and to the letters of reference marks thereon, which form a part of this specification.

p This invention relates to improvements in tires.

Pneumatic tires as constructed While affording the desired amount of resiliency'ar'e easily punctured and are-always short lived. making them very expensive to-maih'taihi] It is an object of this invention toiprovid'c a tireof equal or greater resiliency than a pneumatic tire but 1n which the use of air is avoided thus providing a punctureless tire.

It is a further object of the invention to provide a chea and durable tire easily assembled and e cient in operation.

The invention consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure 1 is a transverse section of a device embodying my invention.

, Fi 2 is an enlarged section taken longitudiratmg ring and inner band or ring.

' integral p the faces of ly of the tire with one of the springs in full lines. Fig. 3 is a fragmentary side elevation of the separating ring. Fig. 4 is a fragmentary bottom plan view of the sepashown in said drawings: The felly may be made'of wood, steel, or other suitable material and secured thereon is the rim which comprises a circular bottom band a with which is a side flange a which is directed outwardly and affords part of the retaining means for the tire. Rigidly bolted to the 0 posite side of said rim a is a removable siclh flange a corresponding with the flange a. A separating ring or plate a is secured in acentral peri heral groove in the rim by means of the b0 ts a which secures the removable flan e a in position thus dividing the channel ormed by the flanges to aifor two e ual channels.

The inner aces of the flanges a and a and the separating or dividing ring are provided near the periphery with a concentric shoulder b corrugated on it's under circumference of which is less than that of the erimeter of the shoulder. As shown saidhand is provided with notches to receive the ribs t injtegrahwith the flanges aa. and the-separating ring ail? A corrugated band or,;ring of spring metal D en ages inside of the corrugated shoulders I), an like the ring C is adapted to fit loosely in the channel, and a flat coiled spring E is secured between said bands or rings CD.

Secured in the channels around the corruated spring band D, are solid rubber treads -F provided with side binding wires f'f, as shown in Fig. 1. 1

The operation is as follows: The tire is assembled with the spring bands 0 and D, secured within the res ective shoulders and the tread secured in tlie channel to project the desired distance beyond the flanges and the tension wires prevent the same fromleaving the channel. Inasmuch as said bands are secured loosely in the channels-or in other words are of a diameter less than the diame-- ter of the respective shoulders, pressure on the tread contacting the ground permits the 35 bands to give upwardly and the sides of the bands to yield outwardly until contacting the shoulders reducing the desired degree of resiliency w ich of course may be regulated by the size of the resilient bands. The ribs 72 prevent the band C from moving relatively of the plates and the corrugated shoulders effectively prevent relative movement the resilient band D or ribs may also be provided. When desired for vehicles of narrow tread it is of course obvious that the tire may be made with only one channel or that any desired number of channels "may be provided. It may further be desirable to use either the corrugated or the plain resilient bands singl with the rubber treads and to entirely eliminate the use of the coiled spring. In this case only one shoulder is necessary reatly simplifying the construction. I there ore do not purpose limiting this application otherwise than necessitated by the prior art as the arrangement of parts and details of construction may be varied without departing from the principles of this invention.

the shoulder and a rubber tread secured against the band.

3. A device of the class described comprising a channeled rim of inwardly directed shoulders extendin around the channel, a resilient corrugatef band of metal engaged in the channel within one shoulder, a resilient '3 band of lain metal engaged in thechannel within tie other shoulder, resilient means therebetween and a resilient tread against which one of said bands bears.

4. A resilient tire embracing a rim affording channels, oppositely disposed inwardly directed shoulders on the flanges thereof, a resilient band of metal in each channel within the shoulder adapted toyield upwardly and outwardly when pressure is applied on one side thereof, a rubber tread for said tire coacting with said band and means preventing relative rotation of the rim and resilient bands.

5. In a device of the class described the combination with a rim embracing a channel of a se arating ring dividing the same periphera ly providing a plurality of channels, a corrugated resilient metallic band, in each channel, a resilient metallic band therein, in-

terinediate tne same and base of the channel,

a coiled spring between said bands, a rubber tread for each channel outside the outer band and retaining wires for each rubber tread. i

6. A resilient tire comprising a felly aliording a channel, a resilientspring band, in said channel adapted to yield upwardly, means retaining the band in the channel, a resilient tread secured in and extending beyond the peri hery of the felly and ribs rigidly secured to t 1e flan es to of the band and ielly.

7. in a device of the class described a felly revent relative movement having side flanges afiordinga channel therebetween and one of the flanges being removable, means rigidly securing the removable flange to the felly, inwardly facing shoulders rovided by said flanges, hands. of resilient metal in the channel one loosely engaged beneath each shoulder, resilient means between the shoulders and a rubber tread extending beyond the flanges.
